1N963B Description

Short technical summary and product information.

The 1N963B is a 12V Zener diode from On Semiconductor, part of the 1N957B-1N979B series. It offers a nominal Zener voltage of 12V with ±5% tolerance and a maximum power dissipation of 500mW at lead temperature ≤75°C. The device features a maximum Zener impedance of 11.5Ω at the Zener test current and a reverse leakage current of 5µA at 9.1V.

 

This Zener diode is designed for voltage regulation and protection circuits in a wide range of electronic applications. It operates over a temperature range of -65°C to 200°C, making it suitable for demanding environments. The maximum Zener current is 28mA.

 

The 1N963B is housed in a DO-35 (DO-204AH) axial leaded glass package, designed for through-hole mounting. The cathode is identified by a color band. This package offers reliable performance and ease of assembly in traditional PCB designs.
